30 = 3 x 10
40 = 4 x 10
The GCF of 30 and 40 is 10.
30 x 4 = 120
40 x 3 = 120
The LCM of 30 and 40 is 120.
Oh, dude, you're hitting me with the math questions? Okay, okay, let's see. The LCM of 30, 40, and 60 is 120 because that's the smallest number they can all be divided evenly by. The GCF of those numbers is 10 because it's the largest number that can divide all three of them without leaving a remainder. Math, man, it's like magic but with numbers.
GCF = 10... LCM = 60 !
30 and 40Factors of 30 are 1, 2, 3, 10, 15, and 30.Factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The GCF of 30 and 40 is 10.Multiples of 30 are 30, 60, 90, 120, ...Multiples of 40 are 40, 80, 120, ...The LCM of 30 and 40 is 120.orWrite the prime factorization.30 = 2 x 3 x 540 = 23 x 5The common prime factors are 2 and 5, so that the GCF of 30 and 40 is 2 x 5 = 10.The greatest power of both numbers are 23, 3, and 5, so the LCM of 30 and 40 is 23 x 3 x 5 = 120.
The LCM is 600.
The LCM is 600.
